i. Carbon dioxide (CO2) is a major greenhouse gas when it diffuses into the earth atmosphere. Given that at 273 K and 1 atm, the value of D for CO2 (Dco2) is 1.00 x 10-5 m? s1, calculate the collisional cross-section of the gas. ii. Under the same T and P, the DN2 value of nitrogen gas is three-fold greater than the value of Dco2. Calculate the value of o for N2.

Carbon dioxide (CO2) is a major greenhouse gas when it diffuses into the earth
atmosphere. Given that at 273 K and 1 atm, the value of D for CO2 (Dco2) is 1.00 x 10-5
m? s1, calculate the collisional cross-section of the gas.
Under the same T and P, the DN2 value of nitrogen gas is three-fold greater than the
value of Dco2. Calculate the value of o for N2.
